REUBEN E. NICHOLS, OF PHILADELPHIA, PENNSYLVANIA.

CAR-H EATER.

SPECIFICATION forming part of Letters Patent No. 430,875, dated June 24,1890.

Application filed December 6, 1889- Serial No- 332,'763. (No model.)

To all whom it may concern:

Be it known that I, REUBEN E. NICHOLS, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and nsefulInr provement in Car-Heaters, whichimprove ment is fully set forth in the following specification andaccompanying drawings.

My invention relates to car-heaters; and it consists of theconstruct-ion, arrangement, or combination of the parts, as will be morefully hereinafter set forth and definitely claimed.

Figure '1 represents a vertical section of a locomotive-enginecontaining part of a carheater embodying my invention. Fig. 2 representsa front view of portion of the heater and adjacent parts of the engine.Fig. 3 represents a partial side elevation and partial longitudinalsection thereof. Figs. 4: and 5 represent longitudinal sections ofportions of cars with parts of my invention applied thereto.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings, A designates the smoke or fire box of alocomotive-engine, and B designates a chamber for heating air, the samebeing located in said box and consisting of a suitable casing, to thefront and rear walls of which are secured fines O, which admit thepassage of the products of combustion through the same, it being seenthat the products of combustion also pass around the casing, whereby thecasing will be highly heated without, however, affecting the draft.

I) represents nozzles or pipes, which pass tightly through the shell ofthe boiler, and are connected with the casing of the chamber B, so as tobe in communication therewith and direct air thereinto.

A designates a neck, which unites the two divisions of the chamber B.

E designates pipes, which are attached to the walls of said neck, andwith which are connected blowers or fans F, the latter being located onthe front portion of the truck of the engine or on any other suitableportion thereof, and having connected with them pipes G, which extendalong the engine, and are attached by flexible connections II and shortsections of pipes II with pipes or passages J in the cars K, said pipeshaving branches L, which pass under the car-seats for distribution ofheat ad mitted to the pipes J.

In the cars are radiators M, which are in communication with the pipesII and the pipes or passages J, and contain stoves or other heatingdevices for obtaining heat should the cars be disconnected from theengine or there be any defective action of the heat generated in theengine. The blowers or fans F are operated by a small engine N, suitablylocated on the loco motive-engine, the same being under control of theengineer or fireman, if so desired. It will be seen that as air is drawninto the chamber B it is highly heated by contact with the hot fines Cand walls of said chamber, and from thence it is driven by the blowersor fans into the pipes G, and thus through the couplings II and pipes IIinto the pipes or passages .I the heat entering the radiators M unlessdirectly conveyed by the pipes II into the pipes or passages .I. It willbe seen that the cars will be eifectively heated, the means employedbeing simple and inexpensive, easily applied, and without the dangerattending the use of stoves. I

Connected with the chamber B at or about the place of connection of thepipes E is a valve I, whereby communication of said pipes with thechamber B may be closed, so that heat from said chamber is preventedfrom e11- tering the pipes E. Valves Q are connected with the pipes E,so that fresh. air may be admitted thereinto, whereby provision is madefor directing said air into the cars, thus admirably adapting the deviceto serve as a ventilator or cooler-a feature of service during warmweather.

The shape and location of the chamber B may be varied; hence I do notlimit myself to the same; but the shape of the fines is preferablyelliptical, so as to gain a large heat ing-surface without materiallyaffecting the draft of the furnace.

It is evident that by the use of the coupfor the products of combustion,and increas ing, the heating-surface of said casing and avoidinginterference with the steam-exhaust, draft, &c.

The pipes J and branches L may have suitable registers for controllingthe heat admitted thereinto.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The air-heating chamber B, located in the smoke-box of alocomotive-engine, consisting of a casin g with supply-n ozzleD,centraldivisional Walls forming the passage R, and a neck A,connecting the divisions of the casing, said passage B being in front ofthe lines or tubes of the boiler, substantially as described.

2. The divided chamberB, with air-supply REUBEN E. NICHOLS.
